Question

I am creating an abstract class. I want each of my derived classes to be forced to implement a specific signature of constructor. As such, I did what I would have done has I

not sure if this helps - but i feel this would be a solution to your problem:

public class A
{
  public A(int a, int b)
  {
    DoSomething(int a, int b);
  }

  virtual public void DoSomething(int a, int b)
  {

  }
}

public class B : A
{
  override public void DoSomething(int a, int b)
  {
    //class specific stuff
  }
}

with the result that you can call a constructor with the required arguments in any derived class with the correct behaviour.
